The US PP Water Management Device (WMD) contains an electronically controlled valve and microprocessor with embedded firmware that enables it, when connected to a pulse output water meter, to perform a number of metering functions in addition to those usually associated with a prepaid metering system.

The WMD product is usually housed in a meter box assembly incorporating an incoming stopcock, a water meter, piping and the WMD.

The WMD’s primary function is to monitor and manage domestic water consumption. The water consumption is monitored directly from the pulse output of a conventional water meter via a fully electronic pick up. This ensures high accuracy, reliability and long life. The WMD is also able to interface to standard reed switch and electronic pulse output sensors.

WMD, in addition to the prepayment functionality, can also manage the consumer’s water consumption through the use of a real time clock and an integrated, low power, self-latching diaphragm valve.

The WMD contains a bi-directional radio which can be used to communicate with the WMD and to give it commands. The bi-directional communication ability of the WMD provides the infrastructure to allow for real time control over the consumer’s water supply.
